The fermentation tank module may include: a fermentation case; a fermentation tank which is accommodated in the fermentation case and in which an inner space communicating with the opening is defined; and an insulating part disposed between the fermentation case and the fermentation tank, the insulating part being configured to surround the fermentation tank.

TECHNICAL FIELD

The present disclosure relates to a beverage maker, and more particularly, to a beverage maker having a fermentation tank in which a space for fermenting a beverage is defined.

BACKGROUND ART

Beverages are collectively referred to as drinkable liquids such as alcoholic drinks and teas. For example, the beverages may be classified into various categories including water (drinking water) for solving thirst, a fruit drink having unique scent and taste, a soft drink providing a feeling of refreshment, a favorite beverage expected to have an arousal effect, an alcoholic beverage having an alcoholic effect, and the like.

Beer is a representative example of such beverages. The beer is an alcoholic drink produced by making juice using malt made by sprouting barley, filtering the juice, adding hops to the filtered juice, and then fermenting the juice using yeast.

A consumer may buy ready-made products produced and sold by beer manufacturers or may drink house beer (or craft beer) produced by directly fermenting materials of beer in a house or a bar.

The house beer may be manufactured in various kinds as compared with the ready-made products, and may be manufactured in accordance with tastes of consumers.

Materials for producing beer may include water, malt, hops, yeast, scent additives, and the like.

The yeast may ferment the malt while being added to the malt, and may help to produce alcohol and carbonic acid.

The scent additives correspond to additives such as fruits, syrup, and vanilla beans, which increase taste of the beer.

In general, the house beer may be produced by totally three steps including a wort generating step, a fermentation step, and a mature step, and two weeks to three weeks may be consumed from the wort generating step to the mature step.

It is important that the house beer maintains an optimum temperature during the fermentation step, and as the house beer is manufactured more simply, convenience of a user may be improved.

In recent years, a beverage maker has gradually been used which may easily produce beer in a house or a bar, and it is preferable that such a beverage maker safely and easily produces beer.

Advantageous Effects

According to the preferable embodiment of the present disclosure, the fermentation tank may be adjusted to the optimum temperature by the evaporator and the heater and be insulated by the insulation part. Thus, the beverage material may be made at the optimum fermentation temperature in the fermentation tank, and the completely made beverage may be maintained at the optimum drinking temperature.

Also, the gas generated in the fermentation process of the beverage may be discharged through the gas discharging passage, and thus, the fermentation pressure may be adequately maintained.

Also, the heater may be disposed below the evaporator to generate the natural convection within the fermentation tank, thereby uniformly maintaining the temperature within the fermentation tank.

Also, since the heat insulating member that is hardened to constitute the insulation part is foamed into the fermentation case through the heat insulating member injecting hole, the insulating part may be formed between the fermentation tank and the fermentation case without generating the gap, thereby improving the heat insulation effect.

Also, since the foaming gas discharging hole is formed in the upper surface of the fermentation case, the foaming gas generated from the heat insulating member may be discharged to the foaming gas discharge hole so that the heat insulating member is uniformly foamed within the fermentation case to prevent the heat insulation member from being unfilled.

Also, the upper case body facing the evaporator having the relatively large cross-sectional diameter may have a diameter greater than that of the lower case body facing the heater having the relatively small cross-sectional diameter so that the insulating part has the uniform thickness in the horizontal direction.

Also, since the heat insulating member injection hole faces the portion between the fermentation tank and the fermentation case in the vertical direction, the heat insulating member foamed into the heat insulating member injection hole may decrease in filling pressure that is required for filling the heat insulating member without colliding with the fermentation tank.

While the air injection pump 82 is switched on, the air pumped by the air injection pump 82 may be introduced into the bypass passage 4C through the air injection passage 81, and may be introduced into the beverage making pack 12 through the main valve 9. In this way, the air introduced into the beverage making pack 12 may collide with the liquid malt to help to more evenly mix the malt with the hot water.

As the air is introduced into the beverage making pack 12, the beverage making pack 12 may be expanded, and the part of the air between the beverage making pack 12 and the fermentation tank 112 may be pushed by the expanded beverage making pack 12 to flow to the air supplying passage 154, and may be discharged to the outside through the air discharging valve 156.

When a pressure detected by the pressure sensor 72 is not less than a predetermined pressure, the control module 280 may complete the air injection process, and may switch off the air injection pump 82 for the completion of the air injection process. When the air injection process is completed, the control module 280 may maintain the main valve 9, the bypass valve 35, the gas discharging valve 73, and the air discharging valve 156 in an ON state.

when the secondary hot water supplying process is initiated, the control module 280 may switch on the water supplying pump 52 and the water supplying heater 53. Also, when the secondary hot water supplying process is initiated, the control module 280 may control the passage switching valve 20 such that the first main passage 4A and the bypass passage 4C communicate with each other.

Similar to the primary hot water supplying process, the water in the water tank 51 may be supplied to the beverage making pack 12, and new hot water may be additionally supplied to the beverage making pack 12.

In the above-described secondary hot water supplying process, the beverage making pack 12 may be further expanded by the additionally introduced water, and the part of the air remaining between the beverage making pack 12 and the fermentation tank 112 may be pushed by the expanded beverage making pack 12 to flow to the air supplying passage 154, and may be discharged to the outside through the air discharging valve 156.

The control module 280 may determine whether the secondary hot water supplying process is completed, depending on a flow rate detected by the flow meter 56 during the secondary hot water supplying process. When the flow rate detected by the flow meter 56 arrives at a predetermined flow rate during the secondary hot water supplying process, the control module 280 may determine that the secondary hot water supplying process is completed, may switch off the water supplying pump 52 and the water supplying heater 53, and may switch off the main valve 9, the bypass valve 35, and the gas discharging valve 73.

Further, the control module 280 may perform a control to switch off and close the air discharging valve 156 such that the air in the fermentation tank 112 is not discharged through the air discharging valve 156.

Meanwhile, when the water supplying step S200 is completed, the beverage maker may perform a fermentation tank cooling step S300 of cooling the fermentation tank 112.

The control module 280 may control the temperature controller 11 to cool the fermentation tank 112. In more detail, the control module 280 may control the compressor 131 and the expansion mechanism 133 of the refrigeration cycle device 13 to cool the fermentation tank 112. The refrigerant compressed by the compressor 131 may be condensed by the condenser 132 and then may be expanded by the expansion mechanism 133. The refrigerant expanded by the expansion mechanism 133 may steal heat of the fermentation tank 112 while passing through the evaporator 134, and may be evaporated. The refrigerant passing through the evaporator 134 may be suctioned into the compressor 131. When the compressor 131 is driven, the fermentation tank 112 may be gradually cooled, and the beverage making pack 12 accommodated in the fermentation tank 112 and the liquid malt accommodated in the beverage making pack 12 may be cooled.

When the fermentation tank 112 is cooled as described above, the beverage maker may cool the beverage making pack 12 to a middle temperature, for example, 23° C. to 27° C., and the control module 280 may control the compressor 131 depending on the temperature detected by the temperature sensor 16 installed in the fermentation tank 112. The control module 280 may switch on the compressor 131 when the temperature detected by the temperature sensor 16 exceeds a compressor-on temperature. The control module 280 may switch off the compressor 131 when the temperature detected by the temperature sensor 16 is not more than a compressor-off temperature.

During the fermentation tank cooling step S300, the control module 280 may maintain the air discharging valve 156 closed, the air between the beverage making pack 12 and the fermentation tank 112 is not discharged to the outside through the air discharging valve 156, and the air in the fermentation tank 112 may be quickly cooled.

Exceptionally, when the temperature of the beverage making pack 12 is lower than the middle temperature since the external temperature is very low, the control module 280 may switch on the heater 14 wound on the fermentation tank 112. The control module 280 may switch on the heater 14 when the temperature detected by the temperature sensor 16 is smaller than a heater-on temperature. The control module 280 may switch off the heater 14 when the temperature detected by the temperature sensor 16 is not less than a heater-off temperature.

After the fermentation tank cooling step S300 is initiated and the compressor 131 is switched on as described above, when the temperature detected by the temperature sensor 16 is not more than the compressor-off temperature at least one time, the beverage maker may perform a mixing step S400 of mixing the liquid malt by supplying the air into the beverage making pack 12. Alternatively, after the fermentation tank cooling step S300 is initiated and the heater 14 is switched on as described above, when the temperature detected by the temperature sensor 16 is not less than the heater-off temperature at least one time, the beverage maker may perform the mixing step S400 of mixing the liquid malt by supplying the air into the beverage making pack 12.

Even during the mixing step S400, the beverage maker may perform a control to switch on/off the compressor 131 and the heater 14 depending on the temperature detected by the temperature sensor 16, and the ON/OFF control of the compressor 131 and the heater 14 may continue until additive inputting steps S500, S600, and S700 are completed.

In the mixing step S400, the control module 280 may switch on the air injection pump 82 and switch off the air supplying opening/closing valve 159, and may control the passage switching valve 20 such that the air injection passage 81 and the bypass passage 4C communicate with each other. Also, the control module 280 may switch on the bypass valve 35, the main valve 9, and the gas discharging valve 73. The control module 280 may perform a control to open the air discharging valve 156.

While the air injection pump 82 is switched on, the air pumped by the air injection pump 82 may be introduced into the bypass passage 4C through the air injection passage 81, and then may be introduced into the beverage making pack 12 through the second main passage 4B and the main valve 9. In this way, the air introduced into the beverage making pack 12 may collide with the liquid malt to help to evenly mix the malt and the water with each other, and the air colliding with the liquid malt may supply oxygen to the liquid malt.

While the air is injected into the beverage making pack 12, the beverage making pack 12 may be expanded by the air injected into the beverage making pack 12. The part of the air between the beverage making pack 12 and the fermentation tank 112 may be pushed by the expanded beverage making pack 12 to flow to the air supplying passage 154, and may be discharged to the outside through the air discharging valve 156.

As the part of the air between the beverage making pack 12 and the fermentation tank 112 is discharged through the air supplying passage 154 and the air discharging valve 156, the beverage making pack 12 may be easily expanded, and the air of the main passage 4 may be promptly introduced into the beverage making pack 12 and may be mixed with the liquid malt.

The control module 280 may mix the air with the liquid malt during a predetermined mixing time (for example, one hour) after the air injection pump 82 is switched on, may switch off the air injection pump 82 when the air injection pump 82 is switched on and the predetermined mixing time elapses, and may switch off the bypass valve 35 and the gas discharging valve 73. When the air injection pump 82 is switched off, the control module 280 may perform a control to close the air discharging valve 156. That is, when the predetermined mixing time elapses, the beverage maker may complete the mixing step S400.

The beverage maker may perform the additive inputting steps S500, S600, and S700 after the mixing step S400.

In the additive inputting steps S500, S600, and S700, the beverage maker may simultaneously or sequentially input the additive of the first capsule C1, the additive of the second capsule C2, and the additive of the third capsule C3.

The control module 280 may sequentially perform an additive inputting process S500 for the first capsule C1, an additive inputting process S600 for a second capsule C2, and an additive inputting process S700 for the third capsule C3.

In the additive inputting steps S500, S600, and S700, the control module 280 may control the passage switching valve 20 such that the first main passage 4A and the common dispenser inlet passage 301 communicate with each other.

In the additive inputting process S500 for the first capsule C1, the control module 280 may switch on the water supplying pump 52, the main valve 9, the first opening/closing valve 313, and the gas discharging valve 73 during a first additive setting time. When the water supplying pump 52 is switched on, the water in the water tank 51 may pass through the water supplying pump 52, may pass through the water supplying heater 53, and then may be introduced into the first capsule C1. The water introduced into the first capsule C1 may be mixed with the additive accommodated in the first capsule C1, may flow to the second main passage 4B together with the additive accommodated in the first capsule C1, and may be introduced into the beverage making pack 12 through the second main passage 4B. When the first additive setting time elapses, the control module 280 may switch off the water supplying pump 52 and the first opening/closing valve 313, and may complete the additive inputting process S500 for the first capsule C1.

In the additive inputting process S600 for the second capsule C2, the control module 280 may switch on the water supplying pump 52 and the second opening/closing valve 323 during a second additive setting time. When the water supplying pump 52 is switched on, the water in the water tank 51 may pass through the water supplying pump 52, may pass through the water supplying heater 53, and then may be introduced into the second capsule C2. The water introduced into the second capsule C2 may be mixed with the additive accommodated in the second capsule C2, may flow to the second main passage 4B together with the additive accommodated in the second capsule C2, and may be introduced into the beverage making pack 12 through the second main passage 4B. When the second additive setting time elapses, the control module 280 may switch off the water supplying pump 52 and the second opening/closing valve 323, and may complete the additive inputting process S600 for the second capsule C2.

In the additive inputting process S700 for the third capsule C3, the control module 280 may switch on the water supplying pump 52 and the third opening/closing valve 333 during a third additive setting time. When the water supplying pump 52 is switched on, the water in the water tank 51 may pass through the water supplying pump 52, may pass through the water supplying heater 53, and then may be introduced into the third capsule C3. The water introduced into the third capsule C3 may be mixed with the additive accommodated in the third capsule C3, may flow to the second main passage 4B together with the additive accommodated in the third capsule C3, and may be introduced into the beverage making pack 12 through the second main passage 4B. When the third additive setting time elapses, the control module 280 may switch off the water supplying pump 52 and the third opening/closing valve 333, and may complete the additive inputting process S700 for the third capsule C3.

When all the additive inputting steps S500, S600, and S700 are completed, a dispenser residual water removing step S800 of removing residual water in the dispenser 3 may be performed.

In the dispenser residual water removing step S800, the control module 280 may switch on the air injection pump 82 and switch off the air supplying opening/closing valve 159, and may control the passage switching valve 20 such that the air injection passage 81 and the common dispenser inlet passage 301 communicate with each other. Also, in the dispenser residual water removing step S800, the control module 280 may switch on the first opening/closing valve 313, the second opening/closing valve 323, and the third opening/closing valve 333, and may switch on the main valve 9, and the gas discharging valve 73.

When the air injection pump 82 is switched on, the air may sequentially pass through the air injection passage 81 and the common dispenser inlet passage 301, may be supplied to the first capsule accommodating part 31, the second capsule accommodating part 32, and the third capsule accommodating part 33, and then may blow residual water remaining in the first capsule accommodating part 31, the second capsule accommodating part 32, and the third capsule accommodating part 33 to the second main passage 4B. The air may be moved to the beverage making pack 12 together with the residual water moved to the first capsule accommodating part 31, the second capsule accommodating part 32, and the third capsule accommodating part 33. In the dispenser residual water removing step S800, a controller 109 may open the air discharging valve 156.

As the air is introduced into the beverage making pack 12, the beverage making pack 12 may be further expanded, and the part of the air between the beverage making pack 12 and the fermentation tank 112 may be pushed by the expanded beverage making pack 12 to flow to the air supplying passage 154, and may be discharged to the outside through the air discharging valve 156.

As the part of the air between the beverage making pack 12 and the fermentation tank 112 is discharged through the air supplying passage 154 and the air discharging valve 156, the beverage making pack 12 may be easily expanded, and the air and the residual water of the main passage 4 may be promptly introduced into the beverage making pack 12.

The control module 280 may switch on the air injection pump 82 during a residual water removal setting time, and may switch off the air injection pump 82 and switch off the first opening/closing valve 313, the second opening/closing valve 323, the third opening/closing valve 333, the main valve 9, and the gas discharging valve 73 when the residual water removal setting time elapses. Also, the control module 280 may perform a control to close the air discharging valve 156.

The beverage maker may complete the dispenser residual water removing step S800 when the residual water removal setting time elapses.

When the dispenser residual water removing step S800 is completed, the control module 280 may display a capsule separating message indicating that the capsules C1, C2, and C3 may be removed from the display 282, and the user may remove empty capsules from the dispenser 3.

After the dispenser residual water removing step S800 is completed, the beverage maker may sequentially perform a primary fermenting step S900 and a secondary fermenting step S1000.

In the primary fermenting step S900, the control module 280 may control the compressor 131 and the heater 14 to a primary fermentation target temperature, and may control the compressor 131 and the heater 14 such that the temperature detected by the temperature sensor 16 is maintained in a primary fermentation setting temperature range. After the primary fermenting step S900 is initiated, the control module 280 may periodically switch on and then switch off the gas discharging valve 73, and may store the pressure detected by the pressure sensor 72 in a storage unit (not illustrated) while the gas discharging valve 73 is switched on. When a change in the pressure periodically detected by the pressure sensor 72 exceeds a first fermentation setting pressure, the control module 280 may determine that primary fermentation is completed, and may complete the primary fermenting step S900.

After the primary fermenting step S900 is completed, the control module 280 may initiate the secondary fermenting step S1000. In the secondary fermenting step S1000, the control module 280 may control the compressor 131 and the heater 14 to a secondary fermentation target temperature, and may control the compressor 131 and the heater 14 such that the temperature detected by the temperature sensor 16 is maintained in a secondary fermentation setting temperature range. After the secondary fermenting step S1000 is initiated, the control module 280 may periodically switch on and then switch off the gas discharging valve 73, and may store the pressure detected by the pressure sensor 72 in the storage unit (not illustrated) while the gas discharging valve 73 is switched on. When the change in the pressure periodically detected by the pressure sensor 72 exceeds a second fermentation setting pressure, the control module 280 may determine that secondary fermentation is completed, and may complete the secondary fermenting step S1000.

When both the primary fermenting step S900 and the secondary fermenting step S1000 are completed, the beverage maker may perform a maturing step S1100.

In the maturing step S1100, the control module 280 may stand by during a mature time, and may control the compressor 131 and the heater 14 such that the temperature of the beverage is maintained between an upper limit of a setting mature temperature and a lower limit of the setting mature temperature during the mature time.

Since the beverage maker is generally used indoors, it is general that the temperature of the outside of the beverage maker is between the upper limit of the setting mature temperature and the lower limit of the setting mature temperature or is higher than the upper limit of the setting mature temperature. In this case, the control module 280 may switch off the compressor 131 when the temperature detected by the temperature sensor 16 is not more than the lower limit of the setting mature temperature, and may switch on the compressor 131 when the temperature detected by the temperature sensor 16 is not less than the upper limit of the setting mature temperature.

Exceptionally, when the temperature of the outside of the beverage maker is lower than the lower limit of the setting mature temperature, the control module 280 may switch on the heater 14 when the temperature detected by the temperature sensor 16 is lower than the lower limit of the setting mature temperature, and may switch off the heater 14 when the temperature detected by the temperature sensor 16 is not less than the upper limit of the setting mature temperature.

In the beverage maker, when the mature time elapses, the beverage may be completely produced.

The control module 280 may display completed production of the beverage through the display 282, and the like.

Also, the control module 280 may control the compressor 131 such that the temperature of the fermentation tank 112 is maintained between an upper limit and a lower limit of a predetermined beverage temperature. The control module 280 may switch on the compressor 131 when the temperature detected by the temperature sensor 16 is not less than the upper limit of the beverage temperature, and may switch off the compressor 131 when the temperature detected by the temperature sensor 16 is lower than the lower limit of the beverage temperature. Accordingly, the beverage maker may always provide a cool beverage to the user.

The control module 280 may maintain the temperature of the fermentation tank 112 between the upper limit and the lower limit of the predetermined beverage temperature until a beverage discharging step S1200 is completed.

In the beverage discharging step S1200, the user may manipulate the beverage discharging valve 62 to discharge the beverage.

When the user manipulates the beverage discharging valve 62 in an opened direction, the limit switch 630 may be contacted, and since the beverage is completely produced, the control module 280 may open the main valve 9.

When the main valve 9 is opened, the beverage in the beverage making pack 12 may flow from the beverage making pack 12 to the main passage 4 due to the pressure of the air between the beverage making pack 12 and the fermentation tank 112, and may flow from the main passage 4 to the beverage discharging passage 61 to be discharged to the dispenser 62.

When the user manipulates the beverage discharging valve 62 in a closed direction after discharging a part of the beverage through the beverage discharging valve 62, the limit switch 630 may be uncontacted, and the control module 280 may close the main valve 9.

Thereafter, the control module 280 may perform a control to switch on the air injection pump 82, and to switch on and open the air supplying opening/closing valve 159. At this time, the air discharging valve 156 may be maintained closed.

When the air injection pump 82 is switched on, the air may sequentially pass through the air injection passage 81 and the air supplying passage 154 to be supplied to between the beverage making pack 12 and the fermentation tank 112, and the air between the beverage making pack 12 and the fermentation tank 112 may press the beverage making pack 12 by the pressure by which the beverage in the beverage making pack 12 may be raised to the second main passage 4B. This is for forming a sufficiently high pressure between the beverage making pack 12 and the fermentation tank 112 such that the beverage in the beverage making pack 12 is promptly discharged when the beverage is discharged at a next time.

The user may discharge the beverage through the beverage discharging valve 62 at least one time, and the control module 280 may determine whether the beverage is completely discharged using information on a time when the limit switch 630 is switched on, a time when an air pump 152 is driven, a time when the main valve 9 is switched on after the beverage is completely produced, and the like.

When the beverage is completely discharged, the control module 280 may perform a control to close the air supplying opening/closing valve 159, and to open the air discharging valve 156.

When the beverage is completely discharged, and the beverage discharging valve 62 is closed, the control module 280 switches on and opens the air discharging valve 156 during a completion setting time.

When the control is performed such that the air discharging valve 156 is opened, the air between the beverage making pack 12 and the fermentation tank 112 may be discharged to the air discharging valve 156 through the air supplying passage 154, and a pressure between the beverage making pack 12 and the fermentation tank 112 may be equal to the atmospheric pressure.

After the air discharging valve 156 is switched on, when the completion setting time elapses, the control module 280 switches off and closes the air discharging valve 156.

After the beverage is discharged, when the washing and sterilizing step S1300 is not performed or the washing and sterilizing step S1300 does not include a main passage washing process, the control module 280 may display, on the display 282, a pack removing message to remove the beverage making pack 12. The user may open the fermentation lid 107 to remove the beverage making pack 12 from the fermentation tank module 111.

When the fermentation lid 107 is opened, if the pressure inside the fermentation tank 112 is a high pressure that is larger than the atmospheric pressure by a predetermined pressure, the beverage making pack 12 may bounce to the upper side of the fermentation tank 112 due to such a pressure difference.

On the other hand, when the part of the air between the beverage making pack 12 and the fermentation tank 112 is discharged through the air discharging valve 156 before the user opens the fermentation lid 107, if the fermentation lid 107 is opened, the beverage making pack 12 does not bounce to the upper side, and is maintained inside the fermentation tank 112.

That is, the user may withdraw the safely, cleanly, and previously used beverage making pack 12 from the fermentation tank 112.

Meanwhile, when all the beverage in the beverage making pack 12 is discharged, and the control module 280 determines that the beverage is completely discharged, the control module 280 may further perform the washing and sterilizing step S1300 after the beverage producing course and the discharge of the beverage.

The washing and sterilizing step S1300 after the beverage producing course and the discharge of the beverage may include at least one of a discharging valve washing process and the main passage washing process. When the washing and sterilizing step S1300 includes the discharging valve washing process and the main passage washing process, sequences of performing the washing processes may change as needed.

Since the discharging valve washing process is equal or similar to the above-described washing and the sterilizing step S100 before the beverage producing course, duplicate contents will be omitted. Hereinafter, the main valve washing process will be described.

When the limit switch 630 of the beverage discharging valve 62 is switched off, the control module 280 may switch on the water supplying pump 52 and the water supplying heater 53. Also, the control module 280 may open the main valve 9.

When the main passage washing process is initiated, the control module 280 may switch on the gas discharging valve 73. When the main passage washing process is initiated, the control module 280 may switch on the air discharging valve 156.

The control module 280 may control the passage switching valve 20 to separately or simultaneously wash and sterilize the dispenser 3 and the bypass passage 4C.

For example, the control module 280 may wash and sterilize the bypass passage 4C after washing and sterilizing the dispenser 3.

When the dispenser 3 is washed and sterilized, the control module 280 may control the passage switching valve 20 such that the first main passage 4A and the common dispenser inlet passage 301 communicate with each other, and may switch on the opening/closing valves 313, 323, and 333. When the opening/closing valves 313, 323, and 333 are switched on, the opening/closing valves 313, 323, and 333 may be opened.

When the bypass passage 4C is washed and sterilized, the control module 280 may control the passage switching valve 20 such that the first main passage 4A and the bypass passage 4C communicate with each other, and may switch on the bypass valve 35. When the bypass valve 35 is switched on, the bypass valve 35 may be opened.

When the water supplying pump 52 is switched on, water in the water tank 51 may flow to the water supplying heater 52 and may be heated by the water supplying heater 52.

When the control module 280 controls the passage switching valve 20 such that the first main passage 4A and the common dispenser inlet passage 301 communicate with each other, the water (that is, hot water) heated by the water supplying heater 53 may flow to the first capsule accommodating part 31, the second capsule accommodating part 32, and the third capsule accommodating part 33 through the dispenser inlet passages 311, 321, and 331. The water heated by the water supplying heater 53 may flow to the second main passage 4B after passing through the first capsule accommodating part 31, the second capsule accommodating part 32, and the third capsule accommodating part 33, and may be introduced into the empty beverage making pack 12 inside the fermentation tank 112 through the main passage connector 115.

When the control module 280 controls the passage switching valve 20 such that the first main passage 4A and the bypass passage 4C communicate with each other, the water (that is, the hot water) heated by the water supplying heater 53 may flow to the bypass valve 35 through the bypass passage 4C. The water heated by the water supplying heater 53 may flow to the second main passage 4B after passing through the bypass valve 35, and may be introduced into the empty beverage making pack 12 inside the fermentation tank 112 through the main passage connector 115.

In the main passage washing process, the water performing the washing and sterilizing may be introduced into the beverage making pack 12 emptied after the beverage is completely discharged, the beverage making pack 12 may be expanded by the introduced water, and the part of the air between the beverage making pack 12 and the fermentation tank 112 may be pushed by the expanded beverage making pack 12 to flow to the air supplying passage 154, and may be discharged to the outside through the air discharging valve 156.

When the control is performed as described above, in the beverage maker, the first main passage 4A, the bypass passage 4C, the bypass valve 35, the capsule accommodating parts 31, 32, and 33, the second main passage 4B, and the main passage connector 115 may be washed and sterilized by the water heated by the water supplying heater 53.

The beverage maker may perform the above-described washing and sterilizing during a main passage washing set time, and may complete the main passage washing process after the main passage washing set time.

The control module 280 may switch off the water supplying pump 52 and the water supplying heater 53 after the main passage washing set time elapses, and may close all the main valve 9, the bypass valve 35, the opening/closing valve 313, 323, and 333, the gas discharging valve 73, and the air discharging valve 156.

After the washing and sterilizing step S1300 is completed, the user may open the fermentation lid 107, and may withdraw the beverage making pack 12 containing the water performing the washing from the fermentation tank module 111.
